Check out the awe-inspiring buildings at the Illinois Institute of Technology and understand why many say Mies is the greatest architect of all time.

Mies van der Rohe, founding father of modernism, is one of the most influential architects of the 20th century. The master of International Style ran the famed Bauhaus School before coming to America in 1936, and many of his most important buildings are clustered near the Chicago lakefront. In episode two of “Amazing Spaces,” we take you to the site of the towering figure’s greatest work: The Illinois Institute of Technology.

In the video above, presented by Hugo Boss, Edgar Ramírez first gives you a tour of S.R. Crown Hall, often considered van der Rohe’s finest building. The architecture students use Crown Hall to this day, studying the curriculum laid out by Mies over half a century ago—and you’ll see why. Next, you’ll visit Carr Chapel, AKA the God Box. It’s the only ecclesiastical building Mies ever designed, but perhaps the most striking example of the sublime purity of his work. Get a rare peek inside Frank Lloyd Wright’s epic LA mansion here, and stay tuned for episode three of “Amazing Spaces.”
